GlaxoSmithKline Consumer Nigeria PLC said it plans to focus on its over-the-counter, oral healthcare, and pharmaceutical business in the country. According to the company, the move is part of efforts to improve margins and ensure sustainable growth in the country. Although sales dropped 21 percent in 2016 from 2015 levels, the company reported profit after tax for the year grew 335 percent to N4.2 billion, boosted by the divestment of its drinks business.
